To all whom it may concern.'

Be it known that I, MATT H. WoRLEY, a citizen of the United States, residing at Redlands, in the county of San Bernardino and State of California, have invented new anduseful Improvements in Flume-Grates, of which the following is a specification.

This invention relates to flume gates for shutting od a part or all of the water flowing in an irrigation ditch or fiume, and a main object thereof is to provide a construction, whereby the gate may be opened to any `desired extent and maintained in position without the employment of any locking device.

A further object is to provide a gate that will remain in spring pressed engagement with its seat in a desired "position, and one in which the flow of water passing therethrough may be regulated.

Another object is to provide a gate construction that will not clog or stick with sand, and that obviates the excessive amount of friction usual in gates that operate in guideways.

In the accomplishment of the above objects I preferably employ a concrete gateframe provided with metallic gate-seats embedded `therein', and a sliding gate composed of a plurality of sections maintained in water tight engagement with each other by any suitable means, spring means being secured to the gate to maintain it Ain' spring pressed engagement with its seat, the spring means working in grooves formed on the face of the gate frame opposite the gateseat.

In the drawings attached hereto and forming a part of this specification, Figure l-is a cross section of an earthen flume showing the method of placing the gate therein. Fig. 2-is a sectional'plan of the flume with the gate in place therein taken on line 2--2 of Fig. 1. Fig. 3-is a longitudinal section taken on line 3-3 of F ig. 2.

In the dra-wings, 5 designates a gateframe, preferably formed of concrete or similar material and rectangular in configuration. This frame is adapted to be embedded in the earth which forms the flume herein illustrated, the inner edges whichV The vertical faces of the depression 6 are provided with metal bars 8 which project `fromthe faces thereof t0 form a water tight gate-seat. These'bars are preferably formed of thin metal, so as to present as little frictional surface for the sliding gate as possible.

The gate is preferably formed of a plurality of horizontally disposed sections 9, 10, 11 held in detachable relation with each other by means of tongues and grooves 12, thus 'permitting the Vremoval of as many sections as desired to retard the flow of water passing over the gate when it is in its seated position, as illustrated in the various views of the drawings. Rigidly secured to the lowermost section 11 are a plurality of vertically extending rods 413 which terminate at their upper ends above cross-bar 1-1 in spring members 15, which extend downwardly and bear in grooves 16 formed in the face of the gate-frame. It will be apparent that by means of these spring members 15, the gate may be instantly raised at any desired height, and maintained in that position without the employment of any locking or similar devices, the iow of water against the gate tending to assist the springs in maintaining a water tight engagement of the gate with its seat. It will also be apparent from the above description that I have provided a gate which is simple in construction and which may be eiliciently employed in various situations.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. A Hume gate, comprising a frame provided with a gate-seat, a gate vertically movable therein, and resilient means secured to the gate and acting against said frame to maintain the gate in water' tight engagement with the seat.

2. A flume gate, comprising a frame formed of concrete, a metallic gate-seat embedded therein, a gate composed of a plurality of detachable sections vertically movable therein, and resilient means secured to one of said sections and bearing against the opposite face of said frame to maintain the gate in frictional engagement with its'seat.

3. A flume gate, comprising a rectangular frame formed of concrete and provided with a metallic gate-seat embedded therein and projecting beyond the face of the frame, a

gate composed of a plurality of detachable sections vertically movable therein, and a `talliC gate seat rigidly embedded therein, a pair of springs secured to the lower of said gate slidably mounted in said frame and 15 sections, the upper ends of said springs conacting against said seat, and resilient means tacting With the face of said frame opposite secured to said gate and contacting against the gate-seat. y said frame to maintain said gate in Water 4.
